This ,invention relates to 'improvements 'in hair curlersof the kind adapted to be secured to the hair fora length of time `sumcient `to set the curl, `and `more particularly to hair curlers of: well known commercial type having `a hollow tubular body,]a spring-pressed jaw hinged at one end ,thereoh to grip the free end of thetress, anda wire loop,also `hinged to the body, and adaptedto secure said `curl along opposite lsides of ,thefbody I u One `of theprincipal diiculties commercially encountered with `hair `curlers ofthe type above` described is their tendency to become unfastened while in use, due mainly to insufficient means `for insuring thelocking of the wire loop relative to thetubular body." y r r. I

Ins'uch devices the. wire loop isfusually securedby tension in ajnotch at the upper end of the hollow body, but after the devices have been repeatedly used, said loops tend to become distorted, and the notches worn, so that the loops readily become unfastened.

The object of the present invention is to provide an improved curler of the general type above described, wherein the loop is provided with a positive locking device which may be seourely locked to the e'nd of the tubular body after the curl is formed, and also serves to lock lthe Springpressed jaw against said body, while the curler is in use.

The invention may best be understood by reference to the accompanying drawing, in which- Figure 1 is a perspective view of `a curler made in accordance with my` invention, with a curl formed thereon, but before the wire loop is finally fastened to the end of the tubular body;

Figure 2 is a detail longitudinal section showing the upper end of the curler (with the curl removed), indicating` how the locking cap is swung into position for locking;

`usually made of perforated metal, and Il is a spring-pressed jaw hinged as usual near the `lower end of the tubular body, so that its elongated I laterally curved jaw portion I2 ts along said I body` to secure the end of the tress preparatory to curling the latter. A loop I3, herein formed of flat wire, has its legs E4, I4 hinged as usual near the lower end of the tubular body, concentric with thehinge of the jaw II. The `free upper end `of sadlloop is of suicient length to swing over theft-,opor thetubular body I0.

Referring ,now vmore particularly `to the irn-l proved locking meansof -rny invention, I pro` videa cap or thimble 1.5, of `Slightly larger diameter than thatof the `top` end of 4the tubular body IIJ` and slidably mounted 'onthe upperend portion .I6 of `the loop I3, as is best seen in Fig; ure f1. f In the` form shown, said cap has a pair ofdependinglugs I'I, I 1 at opposite sdesthereof, which have. ,ears I8, ,I8 bent inwardly about the proximate sides `of ,the loop "I 3, as shown, to ipermit limited endwise fsliding`move`ment of "said cap `relative'to said loop. The arrangementis such .that the .cap can be raised toswing overy the top of the body, 'but when in registering position Ltherewth, as shown `in full Vlines in` Figure .2, 4said cap can then be slid downwardly to fit `in locking position over the upper end` of` I said body and the end of the jaw II, as shown in Figures 3 and 4. Said cap is securely held in its locking position by a lug I 9 preferably formed by 'bending the extreme end of the jaw II outwardly. Said lug is adapted to be engaged by tension with a suitable detent on said cap, herein consisting of an aperture 2li, formed in the side of the cap. In the form shown, the cap has a downwardly and outwardly flared portion 20| adjacent the aperture 20, forming in effect a cam surface for depressing said lug as the cap is being moved downwardly into locking position. The lug I9 may be unlocked from the aperture 20 when desired, by depressing the J'aw with the fingers.

r 'I'he upperend portion I6 of the loop I3 which fits within the cap I5 is formed with a bumped portion 2| at its center, which is adapted to engage in an aperture 22 formed in the center of the cap, when the latter is in fully locked position, as shown in Figure 4. This humped portion serves to hold the cap in centered upright position relative to the hollow body and jaw, thus preventing accidental unlocking of the lug I9 by tilting movement of said cap.

The use and operation of the curler above described will now be understood by those familiar with devices of this character.` Usually, the end of the tress to be curled is clamped between the `body I0 and the jaw Il, and the tress is then curled by rotating the curler s0 as to roll the curl about the body and jaw substantially as indicated in Figure l. The loop I3 is then swung over the upper end of the curler, and the cap I5 is slid downwardly over the end of the hollow body and jaw, until the lug I9 snaps into locking position in the aperture 2G. As thus secured, the curler will remain on the curl until it is positively unlocked by depressing the lug I9, as previously described.

Although I have shown and described certain embodiments of my invention, it will be understood that I d0 not wish to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

l. In a hair curler, a body member, a jaw member hinged near one end of said body member, a loop member also hinged near one end of said body member, and an annular locking member slidably mounted on the swinging end of said loop member in position to be moved into surrounding` relation with the adjacent outer ends of said body member and said jaw member respectively, to hold all of said parts in mutually interlocking relation, and means detachably connecting said jaw member and said locking member to prevent endwise disengagement of the latter. y

2. In a hair curler, a body member, a jaw member hinged near one end of said body member, a loop member also hinged near one end of said body member, and a cap member slidably mounted over the swinging end of said loop'member in.

body member, and a cap member sldably mounted.

on the swinging end of said loop member and adapted to enclose the adjacent outer ends of said body member and said jaw member respec-v tively, to hold all of said parts in mutually interlocking relation, and means affording mutually interlocking engagement between the end of said jaw member and said cap member, to prevent endwise disengagement of the latter.

4. In a hair curler, a body member, a jaw member hinged near one end of said body member, a loop member also hinged near one end of said body member, and a cap member slidably mounted on the swinging end of said loop member and adapted to enclose the adjacent outer ends of said body member and said jaw member respectively, to hold all of said parts in mutually interlocking relation, and means affording mutually interlocking engagement between the end of said jaw member and said cap member,r comprising a laterally projecting lug on said jaw member adapted to engage a detent on said cap.

5. In a hair curler, a body member, a jaw member hinged near one end of said body member, a loop member also hinged near one end of said body member, and a cap member slidably mounted on the swinging end of said loop member and 'adapted to enclose the adjacent outer ends of said body member and-said jaw member respectively, to hold al1 of said parts in mutually interlocking relation, means affording mutually interlocking engagement between the end of said jaw member and said cap member, comprising a laterally projecting lug on said jaw member adapted to engage a detent on said cap, and means on said loop movable into interlocking engagement with said cap when the latter is in locking position on said body, to hold said cap against tilting movement relative to the latter.
